Convert TAB to KMZ

Understanding the TAB and KMZ file formats

TAB files are spatial data files used primarily by MapInfo, a popular geographic information system (GIS) software. These files store map data, including vector features and associated attribute information, and are often accompanied by other files such as .DAT, .ID, and .MAP to form a complete dataset.

KMZ files are compressed versions of KML (Keyhole Markup Language) files, used by Google Earth and other mapping applications. KMZ files can contain geographic data, images, and other resources, making them ideal for sharing and visualizing spatial information on web-based platforms.

Why convert TAB to KMZ?

Converting TAB files to KMZ format allows you to share and visualize your spatial data in Google Earth and other applications that support KML/KMZ. This enhances accessibility and presentation, especially for users who do not have access to MapInfo.

How to convert TAB to KMZ

The conversion process involves exporting the spatial data from the MapInfo TAB format to the KMZ format. Here are the recommended steps:

1. Using QGIS (Quantum GIS):
   • Open QGIS and go to Layer → Add Layer → Add Vector Layer to import your TAB file.
   • Once loaded, right-click the layer and select Export → Save Features As....
   • In the Format dropdown, choose Keyhole Markup Language [KML].
   • Set the file extension to .kmz in the output file name to create a compressed KMZ file.
   • Click OK to export your data.
2. Using online converters:
   • Websites like MyGeodata Converter (mygeodata.cloud) allow you to upload TAB files and convert them directly to KMZ format.
   • Simply upload your TAB file, select KMZ as the output format, and download the converted file.

Best software for TAB to KMZ conversion

• QGIS – Free, open-source, and supports a wide range of GIS formats including TAB and KMZ.
• MyGeodata Converter – Convenient online tool for quick conversions without installing software.
• FME Desktop – Professional-grade software for complex GIS data conversions (commercial license required).

Tips for successful conversion

• Ensure all associated files (.DAT, .ID, .MAP) are present with your TAB file for accurate import.
• Check the coordinate reference system (CRS) and reproject if necessary to match your target application's requirements.
• Review the exported KMZ in Google Earth to verify that all features and attributes are correctly displayed.
